[Q] Headphone Jack - Hiss / Static?

I hate bluetooth with a passion. I am a earbud/headset guy.
I noticed when I first got my Skyrocket that there was always a background hiss, like the sound you get out of speakers when it is not shielded good enough.
Any other owners try this? Use the stock headset or iphone earbuds then simply launch an App enough to get it to play a simple sound... do you here a slight hiss for a few seconds after the sound plays?
Also try calling someone using the headset and listen for background noise. I just got a replacement Skyrocket in and it is making the same noise. If I use the speakerphone or Bluetooth it is fine.
My last phone the I had was an Infuse. It is still in my possession and I retested. The hiss is there but it is so quiet I almost could not hear it.
Please let me know if you notice this, it is driving me crazy!

I posted about this shortly after release. Mine does it VERY noticeably, only in the car, only while charging. All 5 skyrockets have done it.
I have found No fix

I can hear it regardless of what the phone is doing. Charging doesn't seem to make a difference as far as I can tell.
Thanks for the feedback in any case. I really... really like the phone other than that.

Its much worse when charging. Search YouTube for "skyrocket feedback'
Oddly enough I can't get it to do it under other scenarios

If you are within your 30 days buyers remorse or have insurance, get it switched out. I believe its a defective issue. I had that happen on my white SGS2SR and I returned it for a new one in box and it no longer has that issue.

I called ATT up and complained. They sent me another skyrocket that is brand new in the box. It also makes the same noise.
I am more curious to hear if anyone else can hear the noise as I have described it.

Skyrocket Hiss
I'm right there with you. Never noticed it until today because thinking back, I haven't used the headphones yet. I was trying to listen to Pandora and noticed a hiss and crackle. It's gotta be interference because i notice it picks up a little when the screen is on. But It happens whenever there's sound that has or is playing. I notice it during quiet parts of videos or songs and when you unlock the phone it hisses for a second (with the unlock sound) and then shuts down until you go to play anything with audio. I can't handle it. Is this on all skyrockets for certain? Software fix? I'm not paying as much as I did for this to be a problem. I know it sounds picky but it really does bother me during use.

I am not sure myself. I can tell you that I had 3 brand new skyrockets lined up and they all made the exact same noises. I ended up selling the one I did not returnes and got a open box Galaxy Nexus from Expansys. I has it's own issues (like the screen) but the audio jack has no problems.

if you have root try installing voodoo control it helps with audio playback

Man that's a bummer. I'm not sure I can give up LTE now that I've had a taste. I'm going in this weekend to the store and will test every phone they have to see if it's maybe a specific batch problem. I have a couple more weeks of my 30 day comfort zone. This phone is just perfect for me apart from that one flaw. Unfortunately I do try to use it for music so I'm having trouble getting over the fact. How do you like the nexus? I was holding out for that when my captivate fell apart.

The noise while charging is normally not a phone issue and will likely happen with a lot of devices. It's the grounding issue with the CAR chargers and the Headphone Aux in.
I been in Car audio for many many years and have competed in IASCA SQ comps. One of the biggest offenses is 'alternator whine'. Isolating any alternator whine from the sound system was always the factor of proper grounding and wiring. If you run your amp power cable, RCA signal cables and speaker cables to where they crossed the powers cable, you're bound to get the noise.
It all depends on the car, the wiring, the grounding etc etc.
My Galaxy s I has an EXCELLENT audio codec/dac and on it's own is a great player. But in my car as soon as I plug in power and use aux, it's unbearable.
Even though the Skyrocket suffers from poor audio on it's own, the whine while plugged into a car's 12v socket is not Skyrockets fault.
Pull your car into your drive way and use a 120v regular charger and then plug the aux into the car, turn on the car.... you won't hear the whine/noise.

All very good info....but out of our 6 android devices and two iPhones....the skyrockets are the only two that do it.

The issues I have had are not while charging, only when using headphones.

I realllly like the Nexus. ICS is great for the most part and it is nice to be able to flash roms that are straight from google.
Also the phone feels a bit more solid and a little heavier (GSM version) than the Skyrocket in a good way. I do have the grey screen issues at low light levels that other people complain about but at >40% brightness it is pretty much a non issue.

Mine does it too, but it doesn't particularly bother me. I think it might even be a software issue, as the hiss cuts out a few seconds after a sound plays.

Isn't that the strangest part!? I think I could get over the fuzz when music is playing, just gotta turn the volume up a bit. But the killer for me was when I tried using the headset during a phone call and it was a lot more noticeable then I dunno I'm just still so in love with everything else about the phone that I've been reluctant to take it back.
I have this hope where maybe we all got the same batch and they're all a bit defective. I'm waiting until as close to my 30 day mark as possible to ask for another one and then we'll see. If it's still a problem then I think I'll just make due and hope it is a software problem.

Okay so new solution! Wait for the Samsung Galaxy S II Skyrocket HD and see if IT has an audio hiss lol. I mean seriously how many models are they gonna push out before it's over. I'd be so mad if i got the original GSII.

Buzzing/Humming Sound

Hey All -
I ran a quick search and didn't find this problem. I wanted to document it for posterity.
My phone makes a buzzing sound. I've seen it in every ROM I've tried so far (seems to be a hardware problem).
The sound is faint, is unaffected by media volume, and goes away when wifi is turned off. The phone appears to shut off the sound hardware when sound hasn't been played for a while in order to save battery. This makes the buzzing stop. But if a notification comes in, or there is a quiet part of a song, you can totally hear it.
It exists regardless of the ROM I have installed.
The sound is like what you'd hear in an older computer with something called crosstalk. Back in the day, (and to an extent still), various components in the hardware would generate EMI and would affect the sound quality in sound cards. For example, I had an Adlib card that would buzz a little every time the hard drive would read/write to disk.
This sounds just like that.
Anyway... just vote in the poll/comment if you're having this problem. Please post to the thread if you have a solution. I'm not expecting much though. I'm pretty sure I'd basically need a new phone for this to go away.

I get a very slight buzzing in my phones, completely unaffected by wifi. Only happens with my CX300 in-ears, any open earphones i havn't heard any noticable buzzing (though have no tried any type of headphones yet). Using Voodoo sound, lowering the amplifier dB gain and putting the media volume up reduces it a touch.
I grabbed a pair of iphone earphones and the nexus s earphones to test it with some more types, no noticeable buzzing. Also, both their sound quality is appalling in comparison to cheap sennheisers.

Yeah, that's different than me. It sounds like your CX300s might be dying.
I've got some Klipsch S4i ear buds and Bose QC3s that both have the same problem. Its loud and clear enough though that I'm sure I could hear it with cheaper headphones.
I can turn the volume all the way to zero and still hear it. When I turn it up, it doesn't make it louder though, which is "nice".
I've been all over the voodoo sound settings and nothing helps.

That's a shame, your phone probably suffers a noticeable case of leakage between the components. Could this possibly be classified as a defect and be fixed/replaced under warranty?
Also, my CX300s have no hiss on a higher quality dac and it was noticeably louder on my old nokia. I guess they're just more sensitive, they are only 16 ohm after all. No drama for me

It might qualify as a defect. I'd have to bug Samsung I guess. I could see Samsung just telling me to deal with it. It doesn't make a lot of business sense to replace a $500 phone because the headphones hiss when wifi is enabled.
It would sure make me a lot happier about buying Samsung stuff in the future though.
That's really weird about your headphones. Unless the audio quality on the CX300s is far superior over the iphone/nexus s ones, I would expect them all to behave the same way. Even then, it would be very subtle. Maybe the Nexus S doesn't ground the headphone jack very well for your headphones?

You could give them a call/email and see how it works out, but you'll probably be left without a phone for a few weeks if you send it so probably not worth it for you either.
Definitely far superior in comparison, but not nearly superior earphones Possibly a grounding issue, could even be just an unlucky set of Sennheisers that i got and have always been like this. They are out and about anyway, take a good beating and have been rock solid. Hopefully soon i'll be getting a decent pair of headphones for home use, funds allowing.

My laptop does the same thing, I'm thinking it is just interference with the headphones and your phone. might also be a lose wire or something in the phone or headphones :/

I know that this is old tread, but I had the same problem and solution might help someone.
In my case, the source of the buzz was charger (poor power supply filtering in cheap switching sources). I bought some cheap car charger/dock, and whenever I plugged my phone into it I would get lots of buzzing noise. Of course, I used it every time when in car, so I did not notice correlation for a while.
Using better charger solved my problem.
If by any chance you are charging your phone while you listening to music and getting lots of buzz, try disconnecting power cable to phone and see if there is noticeable difference. If there is, you found your problem.

Thanks for letting us know grejigl. Although not the source of my particular (non) issue, i can see it helping out someone else down the road.

I'm running on battery power when it happens to me. I'm pretty sure its caused by something related to WiFi because as soon as I shut WiFi off, the buzzing is gone.

My Earphone Jack doing stupid things

I have been using my Atrix 2 from last 4 months. There were just meager issues like network connectivity etc
Recently, I discovered that the voice output through my earphones has marginally decreased i.e. the maximum volume has decreased. I tried using other earphones also but have experienced the same thing. The speakers are doing fine. There seems to be a problem when connecting ear phones only.
Secondly, When I go to Settings/Sounds/Ringtones or any other kind of tones. I get sound from my speaker even when the earphones are plugged in . The sound output is from both speakers and earphones.
However, playing music gives me output from earphones but with less loudness(i.e. max volume)
I am pissed off because I really love listening to music. please help me. What kinda problem is this.

Could be a hardware-related issue. You might want to try to get a replacement, since you say that the phone is still under warranty...

[Q] Is battery affected by bluetooth volume?

While driving I always hook up my cellphone (in this case a Nexus 5) to my car stereo via bluetooth for music streaming. And out of an irrational fear of battery draining too fast, I always keep the cellphone volume as low as possible and rather pump up the volume rocker on the car stereo itself.
Lately I've been wondering if the volume level on the cellphone (while bluetooth streaming) actually makes any difference on battery consumption.
I mean is not like the cellphone speakers are being used, but still getting the cellphone volume up actually makes the car speakers sound louder so... what do you say?
I've search info on this question across the web to no avail (It may be a silly one anyway but still... enlighten me please ).

Can't imagine that it would, since the bluetooth service is running regardless of volume level, and battery usage is predicated on the time the service keeps your phone awake.

While I can imagine that there is a theoretical, but completely miniscule difference in sending audio where the high bits are always zero (it might compress a hair better), I can't believe that it would have any impact on your battery life.
For best audio quality you want to use as many bits as you can when in digital -- less background noise and low-level distortion. That means turning the BT volume up and the car volume down. Unless you've got your tone, bass boost, thump-thump-erator, or other effects turned on, that means basically max BT volume on the phone.

Pretty sure volume control for bluetooth streaming is all done in software, so lowering the volume does nothing but make things hard to hear.
If you're THAT concerned about battery life, having the Bluetooth radio on at all should give you nightmares...

S7 Audio volume very low?

I've heard that the internal DAC in the S7 is really weak, but is it really this weak? When I listen to music with headphones, I have to raise the volume to ~80% just to sound like how ~30-40% would sound on most devices. This is the same with both wired headphones and Bluetooth headphones

Its fine. Much much louder than my previous sony xperia z3 compact

It most certainly is not fine. At roughly 66% volume, I cannot hear anything when I'm on an airplane. I travel a lot for work and have to crank the volume up past 90% just to listen to podcasts when flying.

I have no issues with it. It depends on the source and type of headphone. Stock headphones are not sealing type so there no way it's going to cancel out airplane. Get sealing earphone and it'll be too loud.

I have volume problems too. Actually at 1-3 notches sound gets cut off!
To clarify it goes from decently loud at the 4+ to well I can't hear half the things at 3 (drops in and out). What I can hear is still loud enough. At step 1 I can hear about 20% at the volume in expecting and the rest is silent.
Then to make things worse, call volume keeps resetting to step 2 or 3. I'd take a call and max it out then next call it will be at 2/3 again.. I believe some app is setting the media volume to call volume. But I have no new apps and did not have this problem on S6.

You should try this mod , IF you're rooted and have a custom recovery. Works really well.

I don't use stock headphones and i always use sealing types in airplanes. When I connect to my car via the aux port, i have to run full volume on the phone and two notches down from full volume on the car stereo to match sound levels from my OPO. My stereo settings go from 0-40, i run 38 with the S7. OPO i can set the stereo to 30 and it matches S7 volume.

I've noticed if I have maps or a GPS running after the GPS uses the speaker, it can use the "full" volume again until I remove and plug a auxiliary cable again. It's a dirty work around but it is effective.

Go to sound quality settings and bump the equalizer all the way up. Can also turn on hearing aid assist
